We've used WebEx at work with good results in the past. Supports both video conferencing as well as desktop sharing between clients. People can even dial in to a conference over the phone if they don't have a microphone.

Since you've said this is work-related, the cost at $49/month may not be too bad.

Actually Skype themselves have now come up with a multi-user (up to 9) video conf. Tested it last week and it looks fine. At this writing it's in Beta, with a "free trial", though I can't see how they can charge for it while it's still in Beta...

Where this is an older question... newer advancements have been made in this arena. Google Plus now offers "Hangouts" where you can invite a group of people to a video-conference enabled chat session and interact freely over the web. It's free... and it works quite well.

ooVoo is an iChat-like video conferencing and chat tool for Windows, loaded with useful, powerful tools that make it a viable alternative for small work groups using conference calls and screen-sharing applications.
